A Ball Mill is a rotating drum with dozens of lead balls inside.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
How to calculate the critical speed of rotating drum. Ball Mill Critical Speed I don't think it will be possible to calculate the critical speed because that. Get Price.

The drive sets the milling drum into slow rotation and the bed of milling media is thus activated, i.e. the balls are lifted and then impact back against the bed. Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out.
General Kinematics VIBRA-DRUM® Grinding Mills are proven in dozens of milling applications in the mining and mineral industries..

At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations: The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm.

The grinding works on principle of critical speed. The critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding. ... 6-Pound, Dual Drum Ball Mill (Skylighter #TL5005) Note: ...

The rotation is usually between 4 to 20
If speed of rotation is very high, the balls cling to the drum walls due to centrifugal force. Therefore, intense grinding action is obtained only when drum rotates at critical speed and here the ball mill rotates at a speed which is neither slow nor very high.
